Abstract (en)

[origin: EP0130319A2] For the purification of ethylene oxide or a mixture of ethylene oxide and a fluorinated chlorohydrocarbon, it is proposed to dry the gas and to liquefy it at a pressure above the liquefaction pressure of air; an adsorber (23) containing molecular sieve, silica gel, alugel or the like is used to dry the gas; an oil-free compressor (32) is used to liquefy the gas. <IMAGE>
